PATEN .AUGUST WEBER, SR., OF SCHENECTADY, NEW

YORK, ASSIGNOR TO WEBER ELECTRIC INCANDESCENT-ELECTRIC-LAMP SOCKET.

To all whom it may concern:

Be it, known that I, AUGUST VEBER, St, a citizen of the United States, residing at Schenectady, county of Schenectady, and State of .New York, have invented certain new and useful'Improvements in Incandescent-Electric-Lamp Sockets, of which the following is a specification.

The invention relates to such improvements and consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this specification. Similar characters refer to similar parts in the several figures therein.

Figure l of the drawings is a view in side elevation of my improved incandescent electric lamp-socket without the inclosingcase which forms no part of the present invention. Fig. 2 is a vertical cross-section of the same taken on the broken line 2--2 in Fig. 1. Fig. 3 is a bottom plan view of the same as shown-in Fig. 1. Fig. 4 is a vertical cross-section of the same taken on the broken line 4.4 in Fig. 3. Fig. 5 is a detached view in perspective of a terminal plate, screw and nut. Fig. 6 is a similar view of the terminal plate alone. Fig. 7 is a View of the nut alone. The last three figures are drawn on a relatively large scale.

' My invention relates more particularly to the class of keyless incandescent electric lamp sockets, although it may be employed in key sockets, if desired.

The principal object of the invention is to simplify the assembling and connecting together of certain parts of the interior of the lamp-socket.

Other objects of the invention will appear in connection with the following description.

The interior of my improved lamp-socket has a two-piece insulating base comprising thewashers, 3 and 4, formed of porcelain, or other insulating material, upon which is mounted the usual screw-shell, 5, the two washers and screw-shell-being all securely held together by a pair of screws, 6, each inserted through alined apertures in the two porcelain blocks or washers and the introverted end-flange, v'2', of the screw-shell and the nut, 8, engageable with said introverted flange. The screw-shell, 5, is adapted to Specification of Letters Patent.

Application filed October 1, 1906.

Patented Nov. 21, 1911. Serial No. 336,842.

be connected with one side of the electric circuit by means of a terminal plate, 9, the body of which is located in a peripheral recess, 10, formed in the insulating base, and the shank of which is interposed between the end-flange of the screw-shell and the porcelain block, 4, said shank being apertured to receive the screw, 6, whereby said aperture, 14, formed by cutting away a portion of the screw-shell, 5, and being adapted to ,form a contact for the central lamp terminal. The shank of the plate, 11, is bent approximately at right angles to the body of the plate and is provided with a transverse recess or groove, 15, formed by a bend in the sheet metal of which the plate is formed, which groove is adapted to receive a projection in the form of a rib, 16, formed on the inner face of the porcelain block, 3, said shank being inserted between the two porcelain blocks of the base and clamped tightly therebetween by means 6. Each of the terminal plates, 9 and 11, is provided with a binding screw, 17 whereby a circuit wire may be connected therewith.

It is desirable where a binding-screw is used for connecting a circuit wire to a terminal plate to provide means forconfining the strands of the wire within proper and safe limits. V

In constructing the terminal plate, 11, I employ a comparatively thin, but strong and resilient, sheet-metal, and insert a bind ing-screw, 17, through an aperture therein into a nut, 21,applied to the back of said plate. This nut, 21, is preferably formed with fingers or'lugs, 22, adapted to embrace said plate and project outwardly beyond the same a sufficient distance to confine between them any strands of the circuit-wire "not covered by the head of the bindingscrew. A third finger or lug, 22, on the nut is adapted to be inserted through an aperture, 23, in the body of the plate, 11, and be slightly headed down or riveted to conof the screws nect said nut and plate together. This third lug or finger, 22, may, however, be left projecting a sufficient distance outwardly from the body of the terminal plate'to cooperate with the other fingers or lugs, 22, to confine the strands of the wire.

What I 'claim as new and desire to secure by. Letters Patent is i 1. In an incandescent electric lamp-socket, and in combination, an insulating-base; a screw-shell having an introverted end-flange mounted uponsaid base; a terminal pla'te having a shank interposed between said insulating-base andthe flange on said shell, and having means for connecting therewith a circuit-wire; and a screw and nut adapted to engage, one the porcelain-base and the other said end-flange on the shell, said screw passing through alined apertures in said flange, insulating-base, and the shank of said terminal-plate.

2. In an incandescent electric lamp-socket, and in combination, an insulating-base comprising a pair of blocks of insulating material'; a screw-shell having an introverted end-flange mounted upon the outer basemember; a terminal-plate having a shank locatedbetween said flange and said outer base-member in a recess in the surface of the latter; and a screw and nut adapted to engage, one the inner base-member and the other said flange, said screw passing through alined apertures in said flange, both of said -base-members, and the shank of said terminal-plate.

In testimony whereof, I have hereunto set my hand this 26th day of September, 1906.
